Specification of Letters Patent.

Application filed April 26, 1916. Serial No. 93,585.

Be it known that l, Josue-ir lll/Annan Jones, a citizen of the-UnitedStates, residing at the city of St. Louis, State of Missouri, haveinvented certain new and useful improvements in Metallic BuildingStructures, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming a partof this specification.

This invention relates 1generally to metallic building structures `andmore specifically to an improved construction vtor a structural.memberwhich may be variously employed as a column, strut member and the like.i

As is welllrnown, in various metallic structures, such as nbridges,towers, framing for buildings and the like, numerous mem- Ibers areemployed as columns, struts, or bracing elements, which are so disposedas to carry longitudinal stresses, and the most important factors ofwhich, therefore,- are a .suiiicient amount of metal and such a disposalof same as to have a sufficient radius of gyration to -lend thenecessary stability. In present practice, such members are fre'- quentlyformed as laced or latticed members, common forms ot' which consist oftivo or Iore commercial shapes joined by lacing or latticing of narrowstrips riveted to the members and serving to keep them properly spacedapart to give the necessary stillness or stability.

The principal object of my present vinvention is to provide an improvedconstruction for a structural member of this sort, by virtue 'of whichconstruction the cost of the vmember is -materially decreased, and amemin any of the fashions now commonly employed.

A still further object of my invention is the provision of a structuralmember which is particularly adapted for use in reinforced concreteconstruction, because of the facili- Patentea Juiy 2e, 1919i ties whichit affords for the disposal, accom-.-

modation, and attachment thereto of concrete reinforcing rods.

Other and further objects of my invention will be obvious or pointed outhereinafter, reference Ibeing had to the accompanying drawings forming apart' of this specification, and in which Figure l is a side eleva-tionof a channelmember of a sort which may be employed in the constructionof my improved member;

Fig. la is a cross section thereof;

Fig. 13 is a side elevation of a further modn'ication of my inventiondesigned specically for a pole-` or a post.

Fig. 14 is a front elevation of thesame.

Referring to the drawings more specifically, the various parts `beingdesignated throughout by similar reference characters, 1t will beunderstood that in the manufacture of my improved member, I mayemployany of a wide variety of commercial structural shapes; that illustratedin Figs. l and CIT l beinga simple channel .member having a web lw andmarginal flanges f. As illustrated in Fig. 2, portions of the webs ot'members of the selected form are punched out .or-slotted as shown, thedisplaced portions being deflected to one side ot the normal plane asshown in Figs. 2 and 3, but remaining integral with the web at one end.Two of the members so formed, which I will designate A and Brespectively, arey then placed together as' illustrated in Figs. l andet", with the dellected portions s in contact, and these deflectedportions or spacing strips as l will call them, are secured together, asby spot welding, or riveting, or in any other suitable fashion. Themembers A. and B, as is obvious, may be disposed parallel or indiverging relationship. then connected as described, the .members form aunitary structural member in which the constituent members and B are theprincipalv loa d carrying elements, and the spacing strips u areconnections which maintain the members A and B in proper disposal andrelationsliip. '.lhe structural member so vconstructed will t'orm aneli'ective strut or column, and will possess the' necessary stiffnessand stability against llongitudinal stresses7 and also permit ofconsiderable resistance to transverse and torsional stresses.

Uf course, the width and length o'l" the spacing strips may be varied asdesired, as may also the degree and lorm in which they are deflectedfrom the webs of the members A and l. However, bars formed with spacingstrips 'of' a given length, may be utilized to form structural membersof different radii by varying as desired the distance at which they arespaced apart and the extent to which the spacing strips are over lappedbefore they are connected.

.ln Figs. 5, and 7, I have shown a variety or shapes, all standard,which may be utilized. ln lfig. 5, it will be observed that instead o'f'having the spacing strips deflected from the web in the same directionas the iianges, they are deflected oppositely thereto so that in thecompleted member all the flanges extend outwardly.

In Fig. (i, l illustrate the use of an angle bar as the member A and anI-bcam as the member l. r

ln Fig. 7, I illustrate the use of simple plates as the members A2 andB2.

ln Fig. S, the members A and B3 are the flanges otl a specially shapedchannel which is Uslniped in cross section, and the spacing strips s arepunched out adjacent thc margins ot said flanges.

ln `["ig. i). lV illustrate the manner in which the spacing `:trips maybe connected by rivets, and show also how they may be disposedperpendicular to the webs, or at any desired intern'iediate angle. f

ln Fig. 10, l illustrate a modification -web of the opposite member.

In Fig. l1, l show the spacing strips connected by butt welding.

ln Figs. 12 and 13, I show a construction wherein the spacing strips arelongitudinally corrugated, or provided with a rib, whereby they arematerially stiflened.

In Figs. 13 and 14, I illustrate an application ot' my invention whereinthe members A* and B4 are portions of an integral member which is bentupon itself so as to bring its end portions opposite to each other. Theconnecting strips s are punched from the original member and connected,across between the opposite portions. A cross section of Fig. 13 wouldbe similar to Fig. 7, al` though the member, or' course, could be achannel or other shape.

In members formed in the fashion illustrated and above described, itwillbe observed that two oppositely disposed members, either separate 0rintegral, are used, which members provide the necessary metal to carrythe stress'to which the structural member is designed to be subjected.These oppositely disposed members in my improved structure are connectedby spacing strips, which strips are formed from po'rtions of the membersthemselves. It will be observed, moreover, that while this constructionrequires the use of no material in addition to the original bar membersit forms a structural member of maximum strength for its weight as thedeflected portions or connecting strips are taken from those parts ofthe bar members which are least effective in supplyingstiffness andstability. Besides producing a member having great strength andstability for the amount of material required, this form of constructionmaterially decreases the amount of labor necessary in the manufacture ofstructural members designed for the use contemplated, as it is notnecessary in the manufacture of; my improved structural mcmber to boltup all of the connections pr liminary to the operation of permanentlysecuring the constituent parts together.

It is obvious that this construction is susceptible of wide application,being useful not only as column or strut members in buildingconstructions, but useful alsol as a reinforcement for concrete posts,beams, etc., to which uses it is particularly adapted by virtue otl thefacility with which other forms of reinforcements, such as rods may besociated with it, passed through its apcrlured portions and connected toit.

While I have shown in the drawings a number of forms in which myinvention may be embodied l 'am aware, ol course, that the structure 'issusceptible to further variations, modifications `and adapta-tionswithout departing from the invention, the scope of which is indicated inthe following claims.

What I claim is:l

1. A metallic structural element comprising side bars or load carryingmembers, said members having web portionsoppositely disposed, a seriesot ltongues cut from said web portions and laterally deflected intocoperative relation and joined together to form spacing and bracingconnections between the load carrying members.

2. A metallic structural element comprising side bars or load carryingmembers, said members havin web portions oppositely disposed, pairs cfgtongues oppositely cut from said web portions and laterally deflectedinto cooperative relation and joined together to form spacing andbracing connections between the load carrying members.

3. A metallic structural element comprising side bars or load carryingmembers, said members having web portions oppositely disposed, a seriesof tongues cut from said web portions and laterally deliected intocoperative relation and joined together to form spacing and bracingconnections between the load carrying members, said tongues beingpartially cut so as to leave but one point of connection with the web.

4. A metallic structural element comprising side bars or load carryingmembers, said members having web portions oppositely disposed, a seriesof tongues cut from said web portions and laterally deflected intocooperative relation and joined together to form spacing and bracingconnections between the load carrying members, said tongues bein formedwith beads which operate to sti en them intermediate the load carryingmembers.

5. A metallic structural element comprising side bars or load carryingmembers disposed side by side and spaced apart and having web portionsoppositely disposed, a series of tongues cut from said web portions andlaterally7 deflected into cooperative relation and joined together toform spacing and bracing connections between the load carrying members.

In witness whereof I have hereunto Set my hand this 24th day of April,1916.
